  • Page 91 All manuals and user guides at all-guides.com LUMINANCE PROCESSING DURING RECORDING In R6000 Series video recorders, luminance processing is performed by circuit IV001, LA71500M. Pin 28 of this circuit receives the composite video signal from Pin 3 of input selector IX001. At the output of a clamp stage, the video signal is applied to Pin 35, at a stage of the AGC that reacts only to the amplitude of the synchronisation time signals.

  • Page 93 All manuals and user guides at all-guides.com DETAIL ENHANCEMENT, PRE-EMPHASIS The luminance signal applied to Pin 26 is sent to the detail enhancement circuit. This circuit amplifies high-frequency, low-level signals. This circuit is active in Record Mode only. It then arrives at the non-linear pre-emphasis circuit. Pre-emphasis also increases high- frequency, low-level signals.

  • Page 95 All manuals and user guides at all-guides.com FM MODULATION The luminance signal from the main pre-emphasis stage is sent to the FM modulator. The FM modulator generates a 3.8-MHz frequency for a synchronisation time signal backdrop, and a 4.8-MHz frequency for a 100% white. The colour rotation signal, applied at 66 of IV001, causes a continuous shift of the luminance signal leading to a 1/2-Fh shift of alternate tracks at the FM modulator output.
